In Linux, software can be installed in several ways:
- From source code
- Using package managers
- Through sandboxed systems
- Via manual download of binaries or images
Understanding the available tools helps in managing dependencies, keeping systems secure, and ensuring compatibility across distributions.
1. Package Management
Linux distributions use package managers to automate software installation, upgrade, configuration, and removal. Packages include binaries, configuration files, and dependency metadata.
